Data Ownership Failure Modes in Split-Brain Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub Landscapes

This technical integration and data-ownership blueprint for Multi-Echelon Inventory Optimization (MEIO): Balancing Central DC Pooling vs. Forward Regional Hub Safety Stock Buffers — Bridging Planning Signals to WMS Replenishment and PO Execution (L0659) specifies the exact system-of-record boundaries, canonical data objects, idempotency keys, and message choreography required to govern multi echelon inventory optimization meio execution bridge. When Warehouse Management Systems (WMS), Transportation Management Systems (TMS), Distributed Order Management (DOM), and core ERP ledgers exchange state updates without strict sequence locks, split-brain inventory and duplicate financial postings become inevitable.

At the core of this operational domain lies a non-negotiable engineering principle: Governing Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub (simultaneous network-wide safety stock optimization across Central Distribution Centers (CDCs), Regional DCs (RDCs), and forward fulfillment hubs using guaranteed-service or stochastic-service echelon math) across US National Freight, Warehouse & Port Corridors and India Multi-State Industrial, Port & GST Corridors requires replacing post-facto spreadsheet reconciliation with deterministic state-transition gates (ECHELON DAG TOPOLOGY LOCK → LEAD-TIME COVARIANCE GATE → SERVICE-TIME SOLVER CHECK → CENTRAL RISK POOL AI → DRP PUSH/PULL DEPLOY GL POST) that hard-lock physical edge capture to statutory filings and ERP sub-ledger settlement. Whenever organizations allow physical warehouse, yard, port, or transit execution to advance faster than digital state verification, the gap between what occurred on the floor and what is recorded in the enterprise ledger widens into structural financial leakage.

The Three Structural Failure Modes of Uncontrolled Execution

In live production audits across US National Freight, Warehouse & Port Corridors and India Multi-State Industrial, Port & GST Corridors, three recurring failure modes explain why legacy SOPs and passive visibility dashboards fail to control Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub (simultaneous network-wide safety stock optimization across Central Distribution Centers (CDCs), Regional DCs (RDCs), and forward fulfillment hubs using guaranteed-service or stochastic-service echelon math):

1. Unverified Physical-to-Digital Handover: Calculating safety stock independently at each of 15 regional hubs using single-echelon formulas, hoarding massive duplicate buffer stock across both the Central DC and forward nodes.
2. Asynchronous Exception Discovery & Commercial Lag: Pushing 100% of slow-moving C-class SKUs to all forward hubs on day one of receipt, trapping inventory in low-demand regions while high-demand hubs stock out.
3. Split-Brain State & Statutory Desynchronization: Ignoring upstream Central DC stockout delay (effective replenishment lead time) when sizing downstream forward-hub reorder points.

Core Control Thesis (L0659): You cannot fix a missing physical control gate at 01 · ECHELON DAG TOPOLOGY (ECHELON DAG TOPOLOGY LOCK) or 02 · LEAD-TIME COVARIANCE (LEAD-TIME COVARIANCE GATE) with an accounting spreadsheet or an LLM chatbot at month-end. Deterministic execution locks must fire at the exact millisecond of physical custody or state transfer, while bounded AI agents (CENTRAL RISK POOL AI) accelerate exception evidence assembly for accountable human sign-off (DRP PUSH/PULL DEPLOY GL POST).

End-to-End Integration Topology and Message Sequence Flow

To eliminate silent state drift across Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub (simultaneous network-wide safety stock optimization across Central Distribution Centers (CDCs), Regional DCs (RDCs), and forward fulfillment hubs using guaranteed-service or stochastic-service echelon math), the execution architecture enforces five sequential control gates linking edge hardware capture (Network BOM & echelon lead-time matrices, inter-facility transfer lane transit-time variance logs, SKU holding-cost tiers, and ERP/DRP deployment tables) and bilateral protocol exchanges (Network BOM & echelon lead-time matrices, inter-facility transfer lane transit-time variance logs, SKU holding-cost tiers, and ERP/DRP deployment tables) directly to the ERP financial sub-ledger:

Stage-by-Stage Control Gate Walkthrough

• 01 · ECHELON DAG TOPOLOGY (Physical Edge & Sensor Capture): Captures primary physical telemetry (MIT Graves-Willems Guaranteed-Serv in the US; India Hub-and-Spoke Mother Warehou in India) and enforces ECHELON DAG TOPOLOGY LOCK via two hard predicates: Verify Network BOM & echelon lead and Block manual keyboard bypass. No downstream document or wave release can initialize until this gate commits.
• 02 · LEAD-TIME COVARIANCE (Statutory & Schema Gate): Validates commercial and statutory dispatch/execution prerequisites (CSCMP multi-echelon network design; GST IGST stock-transfer cash-flow ) under LEAD-TIME COVARIANCE GATE. The system verifies Validate inter-facility transfer and Enforce pre-dispatch compliance lock before opening the physical yard gate, releasing the pick wave, or transmitting the customs/carrier filing.
• 03 · SERVICE-TIME SOLVER (Variance & SLA Tolerance Check): Evaluates in-transit, receiving, or billing settlement events (and US GAAP inventory carrying-cos; and e-Way Bill transit slotting) through SERVICE-TIME SOLVER CHECK. Whenever Evaluate Risk-Pooling Square-Ro or Bifurcate disputed variance lines detects a deviation outside tolerance, the transaction is bifurcated—isolating the disputed variance while preserving flow for verified units.
• 04 · CENTRAL RISK POOL (Bounded AI Evidence Triage): Invokes CENTRAL RISK POOL AI (US Exception & Claim Dossier Draft; India COF & GST Exception Dossier) to correlate multi-source logs, photos, and tariff clauses (Assemble multi-source audit dossier). Critically, this layer enforces Read-Only AI (Zero ERP GL Write)—the AI agent has zero write authority over operational locks or general-ledger tables.
• 05 · DRP PUSH/PULL DEPLOY (Three-Way Sub-Ledger Settlement): Finalizes the three-way tie-out (US GAAP Sub-Ledger & AP/AR Tie-Out; Ind AS & GSTN IRN-Linked Settlement) under DRP PUSH/PULL DEPLOY GL POST, executing Controller cryptographic sign-off and Post net verified USD / INR voucher only after cryptographic and human controller sign-off criteria are satisfied.

Mathematical Invariants for Cross-System Reconciliation: Risk-Pooling Square-Root Law & Multi-Echelon Guaranteed-Service Buffer

Replacing subjective operator judgment with deterministic software locks in Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub (simultaneous network-wide safety stock optimization across Central Distribution Centers (CDCs), Regional DCs (RDCs), and forward fulfillment hubs using guaranteed-service or stochastic-service echelon math) requires explicit mathematical formulations embedded inside WMS / TMS Execution Engine and ERP Financial Sub-Ledger. Below is the complete three-part Risk-Pooling Square-Root Law & Multi-Echelon Guaranteed-Service Buffer governing multi echelon inventory optimization meio execution bridge:

1. Risk-Pooling Square-Root Law & Multi-Echelon Guaranteed-Service Buffer — Primary Physical-to-Digital Conservation

$$SS_{\text{pooled}} = SS_{\text{decentral}} \cdot \frac{\sqrt{\sum_{k=1}^{N} \sigma_k^2 + 2\sum_{i<j}\text{Cov}(D_i, D_j)}}{\sum_{k=1}^{N} \sigma_k}$$

Operational Interpretation & Gate Enforcement: Where $S_{\text{in},m}$ is inbound quoted service time from upstream echelon, $L_m$ is local processing/transit lead time, $S_{\text{out},m}$ is outbound service time promised to downstream nodes, and $S_{\text{in},m} + L_m - S_{\text{out},m} \ge 0$ is net echelon exposure. This primary formulation governs simultaneous network-wide safety stock optimization across Central Distribution Centers (CDCs), Regional DCs (RDCs), and forward fulfillment hubs using guaranteed-service or stochastic-service echelon math using real-time telemetry from Network BOM & echelon lead-time matrices, inter-facility transfer lane transit-time variance logs, SKU holding-cost tiers, and ERP/DRP deployment tables. In production deployments across US National Freight, Warehouse & Port Corridors and India Multi-State Industrial, Port & GST Corridors, this equation is evaluated synchronously at ECHELON DAG TOPOLOGY LOCK and LEAD-TIME COVARIANCE GATE before any physical movement or external message transmission is committed.

2. Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub — Variance Exposure & SLA Threshold Predicate

$$SS_m = z_{\alpha} \sigma_m \sqrt{S_{\text{in},m} + L_m - S_{\text{out},m}}$$

Operational Interpretation & Gate Enforcement: Evaluates real-time operational, physical, and commercial tolerance thresholds across MIT Graves-Willems Guaranteed-Service MEIO model and India Hub-and-Spoke Mother Warehouse (Bhiwandi/Bilaspur/Hoskote) to State CFA / Dark-Store stock deployment to prevent pushing 100% of slow-moving C-class SKUs to all forward hubs on day one of receipt, trapping inventory in low-demand regions while high-demand hubs stock out. By evaluating this expression automatically within DeterministicStateLock / ControlGateLedger and CompliancePayloadRecord (ASC X12 / GSTN-ULIP), the platform eliminates manual spreadsheet guesswork and immediately quantifies the financial or operational exposure at SERVICE-TIME SOLVER CHECK.

3. Three-Way Sub-Ledger Settlement & Audit Lock Predicate

$$\mathcal{G}_{\text{release}}(t) = \mathbb{I}\!\left(\Delta_{\text{edge}}(t) = 0\right) \cdot \mathbb{I}\!\left(\text{Statute}_{\text{US/IN}}(t) = \text{VALID}\right) \cdot \mathbb{I}\!\left(\text{SignOff}(t) = 1\right)$$

Operational Interpretation & Gate Enforcement: Binary settlement interlock ensuring that ERP general-ledger vouchers and statutory filings execute only when physical edge capture, regulatory schema validation, and human controller sign-off are simultaneously satisfied—eliminating ignoring upstream Central DC stockout delay (effective replenishment lead time) when sizing downstream forward-hub reorder points. This binary/threshold predicate serves as the hard interlock for DRP PUSH/PULL DEPLOY GL POST, ensuring that ThreeWaySettlementMatch & VarianceHoldQueue never releases an unverified settlement or corrupts inventory/cost valuation.

Canonical Data Objects, Primary Keys, and Write-Authority Matrix

In a distributed supply chain landscape governing Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub (simultaneous network-wide safety stock optimization across Central Distribution Centers (CDCs), Regional DCs (RDCs), and forward fulfillment hubs using guaranteed-service or stochastic-service echelon math), integration failures rarely stem from network downtime; they stem from ambiguous write authority and missing idempotency guarantees across Edge Capture & Telemetry Layer, WMS / TMS Execution Engine, Statutory & EDI Messaging Hub, ERP Financial Sub-Ledger. The matrix below defines the canonical data contract for every integration boundary:

Event-Driven Integration Invariants

1. Strict Monotonic State Versioning (StateVer): Every state mutation on DeterministicStateLock / ControlGateLedger increments a monotonically increasing integer StateVer. If an asynchronous webhook or EDI message arrives with msg.StateVer <= current.StateVer, the integration broker drops the duplicate payload and logs an idempotent no-op rather than regressing state.
2. Bi-Directional Checksum Binding: Outbound statutory and commercial documents (Network BOM & echelon lead-time matrices, inter-facility transfer lane transit-time variance logs, SKU holding-cost tiers, and ERP/DRP deployment tables) embed a cryptographic hash of the underlying ImmutableScanEvent / DeviceTelemetryPacket line items. When the counterparty returns an acknowledgment or invoice (and US GAAP inventory carrying-cos / and e-Way Bill transit slotting), SERVICE-TIME SOLVER CHECK verifies that the line-item hash and unit totals match before permitting DRP PUSH/PULL DEPLOY GL POST.

Idempotent API, ASC X12 EDI, and India ULIP/GSTN Payload Contracts

To guarantee zero message loss and zero duplicate processing across Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub (simultaneous network-wide safety stock optimization across Central Distribution Centers (CDCs), Regional DCs (RDCs), and forward fulfillment hubs using guaranteed-service or stochastic-service echelon math), integration architects must enforce strict payload contracts across both US (MIT Graves-Willems Guaranteed-Service MEIO model, CSCMP multi-echelon network design benchmarks, and US GAAP inventory carrying-cost & working-capital ROIC metrics) and Indian (India Hub-and-Spoke Mother Warehouse (Bhiwandi/Bilaspur/Hoskote) to State CFA / Dark-Store stock deployment, GST IGST stock-transfer cash-flow optimization, and e-Way Bill transit slotting) data exchanges:

Canonical Event Envelope & Idempotency Specification

Every asynchronous message exchanged between Edge Capture & Telemetry Layer, WMS / TMS Execution Engine, Statutory & EDI Messaging Hub, and ERP Financial Sub-Ledger must carry the following deterministic header fields:

• event_id: UUIDv7 (time-ordered) generated at the physical capture edge.
• idempotency_key: Deterministic SHA-256 digest of (tenant_id + entity_id + stage_code + state_version + capture_hash).
• stage_gate: Enumerated stage identifier (STAGE_01_ECHELON_DAG_TOPOLOGY_LOCK through STAGE_05_DRP_PUSH_PULL_DEPLOY_GL_POST).
• market_regime: US_FEDERAL_COMMERCIAL (CSCMP multi-echelon network design / and US GAAP inventory carrying-cos) or IN_STATUTORY_GST_ULIP (GST IGST stock-transfer cash-flow / and e-Way Bill transit slotting).
• verification_predicates: Boolean assertion map confirming Verify Network BOM & echelon lead, Validate inter-facility transfer , and Evaluate Risk-Pooling Square-Ro before ThreeWaySettlementMatch & VarianceHoldQueue accepts the posting.

Dead-Letter Queue Triage, Out-of-Order Event Handling, and AI Schema Mapping

A defining architectural requirement across all modern supply chain implementations is the strict separation between deterministic transactional locks and bounded AI orchestration:

• Deterministic Execution Engine (WMS / TMS Execution Engine & ERP Financial Sub-Ledger): Owns all state transitions across ImmutableScanEvent / DeviceTelemetryPacket, DeterministicStateLock / ControlGateLedger, CompliancePayloadRecord (ASC X12 / GSTN-ULIP), and ThreeWaySettlementMatch & VarianceHoldQueue. It evaluates Risk-Pooling Square-Root Law & Multi-Echelon Guaranteed-Service Buffer with zero probabilistic variance and enforces ECHELON DAG TOPOLOGY LOCK, LEAD-TIME COVARIANCE GATE, SERVICE-TIME SOLVER CHECK, and DRP PUSH/PULL DEPLOY GL POST.
• Bounded Read-Only AI Layer (04 · CENTRAL RISK POOL · CENTRAL RISK POOL AI): Operates exclusively on read-replicas and unstructured document stores. When SERVICE-TIME SOLVER CHECK flags an exception (Evaluate Risk-Pooling Square-Ro), the AI layer executes Assemble multi-source audit dossier—parsing OCR PDFs, matching dock/yard camera frames, extracting relevant clauses from MIT Graves-Willems Guaranteed-Service MEIO model, CSCMP multi-echelon network design benchmarks, and US GAAP inventory carrying-cost & working-capital ROIC metrics or India Hub-and-Spoke Mother Warehouse (Bhiwandi/Bilaspur/Hoskote) to State CFA / Dark-Store stock deployment, GST IGST stock-transfer cash-flow optimization, and e-Way Bill transit slotting, and pre-populating a structured exception brief.
• Immutable Guardrail (Read-Only AI (Zero ERP GL Write)): The AI agent service principal is denied database INSERT, UPDATE, or DELETE privileges on inventory balances, rate cards, customs filings, and ERP AP/AR sub-ledgers. Every commercial claim, tariff override, or statutory filing requires explicit cryptographic sign-off by the designated human role owner.

Dual-Market Integration Stress Test: Worked US ($) and India (₹) Payload Reconciliation

To ground Multi-Echelon Inventory Optimization (MEIO): Balancing Central DC Pooling vs. Forward Regional Hub Safety Stock Buffers — Bridging Planning Signals to WMS Replenishment and PO Execution in concrete operational economics, the worked scenarios below trace how deterministic control gates eliminate structural leakage in both a high-volume United States corridor and a high-velocity Indian logistics network:

United States Worked Scenario (US National Freight, Warehouse & Port Corridors)

• Facility & Operating Profile: US Production Network (L0657 — Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub).
• Baseline Throughput & Financial Footprint: National aftermarket auto-parts network (1 Central DC, 6 Regional DCs, 85 hubs; $110M inventory) shifting from independent single-echelon buffers to MEIO risk pooling, freeing $16.4M cash while raising fill rate to 98.4%.
• Pre-Control Legacy Failure & Leakage: Uncontrolled exposure to calculating safety stock independently at each of 15 regional hubs using single-echelon formulas, hoarding massive duplicate buffer stock across both the Central DC and forward nodes and pushing 100% of slow-moving C-class SKUs to all forward hubs on day one of receipt, trapping inventory in low-demand regions while high-demand hubs stock out across US operations.
• Deterministic Control-Gate Intervention & Verified Outcome: Deterministic control gate enforcement across National aftermarket auto-parts network (1 Central DC, 6 Regional DCs, 85 hubs; $110M inventory) shifting from independent single-echelon buffers to MEIO risk pooling, freeing $16.4M cash while raising fill rate to 98.4%.
• Statutory & Protocol Audit Trail: Full alignment across MIT Graves-Willems Guaranteed-Service MEIO model, CSCMP multi-echelon network design benchmarks, and US GAAP inventory carrying-cost & working-capital ROIC metrics., linking ImmutableScanEvent / DeviceTelemetryPacket (MIT Graves-Willems Guaranteed-Serv) through ThreeWaySettlementMatch & VarianceHoldQueue (US GAAP Sub-Ledger & AP/AR Tie-Out).

India Worked Scenario (India Multi-State Industrial, Port & GST Corridors)

• Facility & Operating Profile: India Production Network (L0657 — Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub).
• Baseline Throughput & Financial Footprint: Indian consumer-durables & appliance brand operating 2 Mother Hubs and 28 state CFAs, centralizing slow-moving SKUs at Mother Hubs and optimizing echelon buffers to cut network inventory days from 58 to 41.
• Pre-Control Legacy Failure & Leakage: Uncontrolled exposure to calculating safety stock independently at each of 15 regional hubs using single-echelon formulas, hoarding massive duplicate buffer stock across both the Central DC and forward nodes and pushing 100% of slow-moving C-class SKUs to all forward hubs on day one of receipt, trapping inventory in low-demand regions while high-demand hubs stock out across Indian corridors.
• Deterministic Control-Gate Intervention & Verified Outcome: Deterministic control gate enforcement across Indian consumer-durables & appliance brand operating 2 Mother Hubs and 28 state CFAs, centralizing slow-moving SKUs at Mother Hubs and optimizing echelon buffers to cut network inventory days from 58 to 41.
• Statutory & Protocol Audit Trail: End-to-end compliance with India Hub-and-Spoke Mother Warehouse (Bhiwandi/Bilaspur/Hoskote) to State CFA / Dark-Store stock deployment, GST IGST stock-transfer cash-flow optimization, and e-Way Bill transit slotting., binding ImmutableScanEvent / DeviceTelemetryPacket (India Hub-and-Spoke Mother Warehou) to ThreeWaySettlementMatch & VarianceHoldQueue (Ind AS & GSTN IRN-Linked Settlement).

Statutory Audit-Trail Persistence Across US and Indian Regimes

An integration architecture for Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub (simultaneous network-wide safety stock optimization across Central Distribution Centers (CDCs), Regional DCs (RDCs), and forward fulfillment hubs using guaranteed-service or stochastic-service echelon math) is incomplete if its message logs cannot withstand a federal regulatory inspection or statutory tax audit several years after transaction execution:

• US Audit-Trail Persistence (US National Freight, Warehouse & Port Corridors): To satisfy MIT Graves-Willems Guaranteed-Service MEIO model, CSCMP multi-echelon network design benchmarks, and US GAAP inventory carrying-cost & working-capital ROIC metrics., the integration broker must archive immutable, WORM-compliant (Write-Once-Read-Many) copies of every ImmutableScanEvent / DeviceTelemetryPacket, CompliancePayloadRecord (ASC X12 / GSTN-ULIP) (CSCMP multi-echelon network design / and US GAAP inventory carrying-cos), and ThreeWaySettlementMatch & VarianceHoldQueue settlement record, indexed by load/order ID, lot/LPN, and cryptographic SHA-256 payload digest.
• India Audit-Trail Persistence (India Multi-State Industrial, Port & GST Corridors): To satisfy India Hub-and-Spoke Mother Warehouse (Bhiwandi/Bilaspur/Hoskote) to State CFA / Dark-Store stock deployment, GST IGST stock-transfer cash-flow optimization, and e-Way Bill transit slotting., the system must retain complete JSON/XML request-and-response envelopes for GST IGST stock-transfer cash-flow , and e-Way Bill transit slotting, and Ind AS & GSTN IRN-Linked Settlement across the statutory 8-year GST/Customs retention window, preserving the exact linkage between physical gate/dock scans and financial tax notes.

Cutover Verification Protocol and Related Integration Blueprints

Before certifying Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub (simultaneous network-wide safety stock optimization across Central Distribution Centers (CDCs), Regional DCs (RDCs), and forward fulfillment hubs using guaranteed-service or stochastic-service echelon math) (L0659) for production operation across US National Freight, Warehouse & Port Corridors and India Multi-State Industrial, Port & GST Corridors, engineering, operations, and finance leaders should verify the following six control invariants:

1. Edge Capture Integrity: Confirm that Network BOM & echelon lead-time matrices, inter-facility transfer lane transit-time variance logs, SKU holding-cost tiers, and ERP/DRP deployment tables writes immutable events to ImmutableScanEvent / DeviceTelemetryPacket and that ECHELON DAG TOPOLOGY LOCK blocks any transaction violating Verify Network BOM & echelon lead or Block manual keyboard bypass.
2. Pre-Release Statutory Gate: Verify that LEAD-TIME COVARIANCE GATE validates CSCMP multi-echelon network design (under MIT Graves-Willems Guaranteed-Service MEIO model, CSCMP multi-echelon network design benchmarks, and US GAAP inventory carrying-cost & working-capital ROIC metrics) and GST IGST stock-transfer cash-flow (under India Hub-and-Spoke Mother Warehouse (Bhiwandi/Bilaspur/Hoskote) to State CFA / Dark-Store stock deployment, GST IGST stock-transfer cash-flow optimization, and e-Way Bill transit slotting) with Validate inter-facility transfer and Enforce pre-dispatch compliance lock enforced prior to physical dispatch or wave release.
3. Mathematical Tolerance Engine: Validate that all three equations of Risk-Pooling Square-Root Law & Multi-Echelon Guaranteed-Service Buffer (*Risk-Pooling Square-Root Law & Multi-Echelon Guaranteed-Service Buffer — Primary Physical-to-Digital Conservation*, *Multi-Echelon Inventory Optimization (MEIO): Central DC vs. Forward Hub — Variance Exposure & SLA Threshold Predicate*, *Three-Way Sub-Ledger Settlement & Audit Lock Predicate*) execute deterministically inside DeterministicStateLock / ControlGateLedger and CompliancePayloadRecord (ASC X12 / GSTN-ULIP).
4. Automated Variance Split: Ensure SERVICE-TIME SOLVER CHECK evaluates Evaluate Risk-Pooling Square-Ro and Bifurcate disputed variance lines in real time, isolating disputed lines without stalling undisputed settlement flows.
5. Read-Only AI Segregation: Audit RBAC permissions for CENTRAL RISK POOL AI to verify that Assemble multi-source audit dossier operates strictly under Read-Only AI (Zero ERP GL Write) with zero direct write access to ThreeWaySettlementMatch & VarianceHoldQueue.
6. Three-Way Sub-Ledger Close: Confirm that ThreeWaySettlementMatch & VarianceHoldQueue enforces DRP PUSH/PULL DEPLOY GL POST (Controller cryptographic sign-off; Post net verified USD / INR voucher) with complete US ($) and India (₹) audit-trail persistence.
